As explained above, this is not a kata issue. Read about currying

ik bout my solution cuz I was attempting it, wasn't gonna be my final answer yet

There are two problems:

• Problem with tests is that it does not verify whether what you return is a function,
• Problem with your solution that it does not do what is asked.

The description says: "Create a function [...] that returns a callable function object.". Your solution returns something else.

TypeError: rAvgSol is not a function
at Context. (test.js:16:23)
